Specification of Letters Patent.

Original application filed August 21, 1913, Serial No. 785,885. Divided and this application filed June 10, 1914. Serial No. 844,151.

To all whom it may concern:

Be it known that I, RALPH C. SEYMOUR, a citizen of the United States, residing at Larchmont, in the county of Westchester and State of New York, have invented certain new and useful Improvements in \Veb- Cutting Machines, of which the following is a specification.

The invention relates to sheet handling machines, and more especially for machines for cutting sheets from a web.

The objects and advantages of the invention will in part be set forth hereinafter and will in part be obvious herefrom, and such objects and advantages are attained or eifectuated by the means or instrumentalities set forth in theappended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and forming a part hereof, illustrate one embodiment of the invention, the same serving in connection with the description to explain the principles of the invention.

Of the drawings:

Figure 1 is an elevation, with the front frame removed of a machine embodying the principles of the invention;

Fig. 2 is an elevation, looking at Fig. 1 from the right;

Fig. 3 is an elevation' looking at Fig. 1 from the left; and

Fig. 4 is an enlarged fragmentary view of the slitter shown near the top in the pre ceding figures.

Referring to the accompanying drawings, illustrating by way of example one embodiment of the invention, a mechanism is shown adapted to receive a running web so, although in many of its aspects the invention is adapted to cooperate also upon sheets. In accordance with certain features of the invention, a plurality of webs may be fed or run side by side instea( of a single web 00 as shown in the drawing.

Means are provided by the invention for cutting transversely the paper fed to the machine, cutting a portion of the width of the paper into sheets of one length and the remainder of said width into sheets of a different length. In accordance with one feature of the invention, sheets of a shorter -may be spring-pressed or length are a submultiple of sheets of a longer length. Also in connection with certain features of the invention enumerated, there is provided by the invention means for longitudinally separating the portions of the web which have been cut transversely into different sheet lengths, thereby totally severing such sheets one from another.

As exemplified by the illustrated embodiment, a machine and instrumentalities included therein are provided adapted to operate upon a web a: coming in at the upper part of the machine (see Fig. 1) from a printing press or other machine. As embodied, the web is cut transversely half way, or to the center line of the web, the cuts in one half of the web, so considered, being more frequent than in the other, and in the present embodiment, one half of the web is cut into sheets of half the length of the sheets into which the other half of the web is out. That is, the transverse cuts in one half of the web are made with double the frequency that they are made in the other half.

Referring to the drawings, suitable feeding-in means for the web are provided, such as sets of rollers, 1 and 2, mounted, respectively, on corresponding shafts 3 and 4. Running over said rollers are a series of tapes 5. Suitable tightening devices for the tapes 5 may be provided, such as a series of rollers 6 bearing on the tapes and carried on a shaft 7. Said shaft 7 is mounted in a pair of pivotally mounted arms 9, which yieldingly acted upon in a suitable manner.

The embodied form of cutting means for the paper comprises a shaft 10, rotatably mounted in the machine frame, and carrying a plurality of rotating disks 11. Arranged along the shaft 10, and running from one disk 11 to another, is a web or blade holder 12, suitably recessed to receive the knife or shearing blade 13. On the other side of the paper there is rotatably mounted in the machine frame, a shaft 14, carrying a plurality of disks or heads 15. A web or support 16 extend along the shaft '14 and from one disk 15 to another, and is suitably recessed to hold the companion knife or shear blade 17. In such embodied form, this set of coacting shearing blades 13 and 17 extend entirely across'the machine, that is,

across the entire width of the paper as it is fed past these rotary cutters.

As a part of the embodied rotary cutter device there is provided aweb or support 20, extending longitudinally of the shaft 10 and from one disk or head 11 to another. Said web 20 is recessed to receive a shearing blade or other suitable cutting device, and in accordance with one feature of the invention a cutting or shearing blade 21 is removably mounted in the holder or web 20. Such removable mounting is shown as bolts and nuts 22 which pass through the holder 20 and the blade 21 to hold it in position. The blade, or cutter 21 is thus removable at pleasure, and one side or length of blade or cutter may be substituted for another. In the embodied form, the blade 21 extends from the side of the paper to the center thereof and is adapted to make a transverse cut from the edge to the center, that is, half wa across the paper.

n the opposite side of the paper, a web or blade support 23 is likewise arranged longitudinally of the corresponding shaft 14, and extending from one head 15 to another, and is recessed to hold the blade 24. This shearing blade 24 is likewise removably mounted, and bolt and nut fastenings 25 are shown for this purpose. As tembodied, the blade 24 is of the same size or length as the blade 21, and acts oppositely thereto, that is, it cooperates therewith to make a cut in the paper transversely half way across. The blades 13 and 17 may also be made removable if desired.

If the blades 21 and 24 are half the width of the web, as shown, and the blades 13 and 17 are the full width of web, it will be seen that for each complete rotation of the shafts 10 and 14, the web will receive one cut or severance completely across its width, and that one half of the web or sheet, considered transversely, will receive a second cut or severance, a half revolution apart from the cut made by the blades 13 and 17. In other words, one half of the web or sheet will be cut transversely twice as often and 5 7 into half thelength of the other half of the web or sheet.

. If two webs are run side by side, the sheets 1 would be completely severed from each other i by the transverse cuttings, one set or series -'of sheets being of different size from the other. Means are rovided by the invention, cooperating wlth the transverse severing means, for longitudinally severing a full width web, so as to separate 1t into the sheets of different lengths. In the embodied form of such means, a shaft 30 is rotatably mount- "ed in the machine frame, said shaft carrying a rotary slitting disk 31. A. suitable shaft 4 is likewise mounted in the machine frame, and carries a grooved disk 33, the disk 31- and the disk 33 coiiperating together to slit the web w longitudinally and centrally.

Means are provided for directing the sheets of different sizes to the subsequent mechanisms, and in the embodied form thereof, a series of throat-bars 34 are mounted upon a shaft 35, and an opposing and cooperating set of throat-bars 36 are mounted upon a rod or shaft 37, the sheets passing between these two sets of throat-bars. Mounted beyond or below the cutting devices, and in cooperative relation with the throat-bars, is a set of rotating disks or rollers 38 carried on a shaft 39. Operating against the series of disks or rollers 39 is a similar set of disks or rollers 40, carried on shaft 41. Suitable driving means (not shown) for these disks are provided. The end .of, the web is received between these two sets of driven disks or rollers 38 and 40, and directed forward through the machine. These disks or rollers may be provided, respectively, with cut-away portions 42 and 43, to give a prompt and full release to the tail of the sheets.

In the embodied form there is also provided a second group of cooperating rollers or disks, comprising a set of rollers or disks 50, carried upon a shaft 51, suitably journaled in the machine frame. Cooperating with the set of disks 51 in this second. roup. is a series of disks or rollers 52, carried by a shaft 53, likewise journaled' in the machine frame. Suitable driving means (not shown) are provided for the disks.

The disks-50 and 52 are provided with sidered transversely of the machine, could have their cut away or lower portions alined toward, or facing, the paper as it is fed.

therebetween. Such disks could then be shafts, being released therefrom by suit able means, and as a. suitable series ofset screws, or by a key or keys, as might be found suitable or convenient.

Means are also provided for throwing 0a,:

or rendering inoperative, an entire group or set'of the opposed disks. For this-purpose, the shaft 51'is provided with slidable bearings in the machine frame of suitable form, said bearings being adjustable by means of threaded rods 58, provided wit .suitable nuts 57, and acted sponding springs 58. Similar devices and connections are provided for the series of 11% held from rotation with then respective upon by corre-q" 110 half of two opposed series of disks, conthe herein described mechanism, tures thereof will be clear from I already been said!" ating upon a single web I j 1, said web being. directed throughtthe rothe sheets as being will), thecut intense disks 52, comprising screw-threaded rods 59, having, respectively, nuts 60, and springs 61.

By the construction and arrangement just described the two groups of forwarding disks could operate upon sheets of one length, and one group thereof could operate upon sheets of another length if desired, or one entire group of the opposed disks can be thrown out of action entirely across the width of the web or paper.

Suitable means are provided for receiving the sheets, and for separately receiving and disposing of the sheets of difierent lengths, one form of such devices includes folding and collecting mechanism, the same being claimed and fully described in the parent application Ser. No. 785,885 of which the present application is a division, the"; same reference numerals being used in the;

parent application as are shown on the iold -ii folding folding ing and collecting mechanism of the drawings herewith.

Means are rovided by the invention for severing the oldcd product from the cylinder 80, es eoially where there are a plurality of foling mechanisms 90 for longitudinally dolding sheets delivered thereto from the cylinder 80. Such a severing mechanism is shown in Fig. i only, and as wmprising the rotary slitter 79 carried on shaft 78, mounted in the machine Jit'rame, and driven in suitable-manner, and cooperating with the cylinder 80. ll desired, it could be located to coiiperate with cylinder 70 instead.
